ASME SA182 F317L Forged Stainless Steel Ring Spacer Flange Paddle Spacers

ASTM A182 / ASME SA182 F317L / 1.4449 Stainless Steel Ring Spacer Flanges 

A ring spacer flange, also known as a spectacle blind, is a type of flange fitting that is used to separate or isolate sections of a pipeline. It consists of a pair of metal discs that are joined together by a small, straight piece of metal. When installed in a pipeline between two flanges, a ring spacer flange allows the easy maintenance, inspection or modification of a line. They are essential components in many industrial applications, providing reliable spacing and alignment to ensure the efficient and safe operation of piping systems and equipment.

Types:

1. Ring Spacers: Circular spacers that fit between flanges to maintain a specific gap.

2. Paddle Spacers: Shaped like a paddle, these spacers are used in applications where a more substantial or specific shape is required to maintain spacing.

Benefits:

1. Corrosion Resistance: Stainless steel construction ensures long-lasting performance even in harsh environments.

2. Durability: High strength and resistance to wear and tear make these spacers reliable for long-term use.

3. Precision: Ensures precise spacing and alignment, which is crucial for the proper functioning of piping systems and equipment.

4. Versatility: Available in various sizes and configurations to suit different applications and requirements.

5. Ease of Installation: Designed for easy installation and removal, facilitating maintenance and repairs.
